Abandoned Cart Recovery Software, Ranked by Whether It Can Withhold the Discount

Abandoned cart recovery software watches for shoppers who add items and leave, then sends reminders by email, SMS or push, usually on a fixed schedule with a discount in the second or third message. The tools differ less in channels than in one decision: whether the software can tell that a particular shopper would have returned without the discount.

Relvino replaces the flow stack these tools belong to, so read this as informed but interested. Each product is described in its own words from its own site, the ranking rule works whichever tool you pick, and the discount arithmetic is yours to check against your margins.

What the software actually does

Strip the category to its parts and every tool does four things: capture (know who the shopper is, usually from an email typed at checkout or into a pop-up), detect (notice the cart or checkout was left), remind (email, SMS, push, on a schedule) and incentivize (a code, usually in the later messages). Shopify’s own help center defines the unit most tools work from: “An abandoned checkout refers to a checkout process that remains incomplete, even though the customer has provided their email information.” No email, no abandoned checkout in Shopify’s count; that is why the capture step matters, and why the difference between a cart and a checkout matters (see abandoned cart vs abandoned checkout).

The decision the category skips

Klaviyo’s own guide lays out the standard series: “Email 1: Remind customers about the products in their cart. Email 2: Send a follow-up email with a discount. Email 3: Share a product recommendation.” Recapture’s guide gives a suggested clock: “Send at 30-60 Minutes,” then “Send at 6-12 Hours,” “Send at 24 Hours,” “Send at 48 Hours,” and its advice on the incentive is “Save discounts for the 3rd or 4th email. Keep them small (5-10% or free shipping).” Both vendors know the trap. Recapture warns, “don’t train shoppers to leave carts on purpose.” Klaviyo writes: “If it doesn’t make sense for your brand’s economics to offer an incentive for every abandoned cart, consider segmenting high-value carts and only offering an incentive on those where you stand to make more revenue from a single purchase.”

Read that last sentence again. The advice is to build a segment: carts over a threshold get the code, carts under it do not. That is the closest a flow can come to the real decision, which is not about the cart’s value but about the shopper: would this person have come back anyway? A shopper who abandons every cart and returns two days later without prompting costs the store a 10% code every time the discount fires on schedule. A first-time visitor who priced the item on three other sites needs the code in the first hour or is gone. A flow cannot tell them apart, because the flow sees a cart value, a timer and whatever segment a person defined in advance, and a segment is a rule about the average shopper in it. So the discount is the decision, and the category has outsourced it to a clock.

The tools, ranked by that decision

Ordered by how much of the discount decision the software makes for you, lowest to highest. Facts are from each product’s own pages at the time of writing; the feature lists are theirs, and the ranking is ours.

• Shopify’s built-in abandoned checkout email. Shopify Messaging’s pricing page says “Shopify Messaging is available on the Basic, Grow, Advanced, and Plus plans” and that “abandoned checkout automations are always free and don’t count towards the monthly limit.” An automated email: you “select how much time should pass from when the customer abandons their checkout to when the automated email sends.” Available “only for the Online Store sales channel, and the Buy Button sales channel.” No per-shopper decision; the delay is set once, for everyone.
• Cartly Abandoned Cart Recovery (Shopify app). Listed as “Abandoned cart recovery email automation & email popup,” with email reminders, web push, “Discount offers,” “Custom discount codes,” “Triggers” and “Targeting rules.” A free plan with 100 recovery emails and a Pro plan at $14.99 a month. Rules decide the discount; you write the rules.
• Recapture. “Email and SMS recovery series. Build multi-step flows with full control over timing, content, and rules,” and it “works with Shopify, WooCommerce®, BigCommerce, and Magento.” Full control is the point and the limit: the timing and the incentive are yours to set, per flow, in advance.
• CartStack. Multi-channel: “Abandoned cart emails, browse abandonment emails and more,” “Abandoned cart SMS text message reminders,” “Abandoned cart & browse abandonment push notifications,” plus “Capture emails as they’re typed, site-wide” and “Abandoned Session Replays,” and it “is compatible with every major ecommerce platform.” Capture and diagnosis are the emphasis; the homepage describes channels and capture, not a per-shopper decision about the offer.
• Klaviyo and Omnisend (cart recovery inside a full email platform). Both run abandonment as one flow among many: Omnisend’s homepage lists workflows “for welcome, abandoned cart, post-purchase, and more,” and Klaviyo’s guide mentions “trigger splits” and “conditional splits” that personalize the series “based on event and profile data such as purchase history, cart size, and product preferences.” The branch is a rule a person writes in advance; it is the segment Klaviyo recommends above. Detail in the Klaviyo abandoned cart flow.
• Relvino (the decision made per shopper). Not a cart tool: an agent that runs the store’s owned channels and treats an abandoned cart as one signal among many. For each shopper it decides, in under 80 milliseconds, whether a reminder is warranted, on which channel, at what moment and whether any discount is needed at all, inside margin floors set once. The offer is withheld when the decision is that the shopper would have returned anyway. That is the whole difference.

Side by side

The quoted cells are the vendors’ own words; the rest is our reading of how scheduled recovery works, which any of them is welcome to correct.

• What triggers a message · Cart recovery tools and flows (Shopify, Cartly, Recapture, CartStack, Klaviyo, Omnisend): A cart or checkout left, plus a timer · Relvino: Live shopper signals, read continuously
• Who decides the discount · Cart recovery tools and flows (Shopify, Cartly, Recapture, CartStack, Klaviyo, Omnisend): A person, in advance, in a rule or a segment where the tool offers codes (Cartly, Recapture, Klaviyo) · Relvino: The agent, per shopper, inside a margin floor set once
• Timing · Cart recovery tools and flows (Shopify, Cartly, Recapture, CartStack, Klaviyo, Omnisend): A schedule (Recapture’s guide: 30-60 minutes, 6-12 hours, 24 hours, 48 hours) · Relvino: Per shopper, in under 80 milliseconds
• Channels · Cart recovery tools and flows (Shopify, Cartly, Recapture, CartStack, Klaviyo, Omnisend): Email, with SMS and push on some tools · Relvino: Email, SMS and on-site
• What it learns from · Cart recovery tools and flows (Shopify, Cartly, Recapture, CartStack, Klaviyo, Omnisend): Rules a person writes and revises · Relvino: A Large Retail Model across 10K+ retailers, plus a per-merchant policy
• What a person maintains · Cart recovery tools and flows (Shopify, Cartly, Recapture, CartStack, Klaviyo, Omnisend): Flows, rules and codes · Relvino: Guardrails, set once
• Time to start · Cart recovery tools and flows (Shopify, Cartly, Recapture, CartStack, Klaviyo, Omnisend): Minutes (CartStack: “integrates in a matter of minutes”) · Relvino: About 30 minutes, then a 14-day pilot

A test you can run in your own data

• Count the codes that were not needed. Take last month’s recovered orders that used the flow’s discount. How many of those customers had bought before, without a code, within the previous 90 days? Most of those are margin the timer gave away.
• Count the carts the timer lost. Take the first-time visitors who abandoned and never opened message one. If the first reminder went out at hour two, many of them were already gone; Klaviyo’s own guidance is to “Send your first reminder 2–4 hours after abandonment,” and a price-comparison shopper does not wait that long.
• Put a value on both and compare them to the flow’s recovered revenue. The codes’ discount value and the lost carts’ value, side by side with what the flow recovered. If they are a meaningful share of it, the cart tool is not the problem. The schedule that decides the discount is.

What per-shopper recovery looks like

Relvino runs Observe → Decide → Act on the store’s owned channels. A shopper who leaves a cart is observed alongside everything else they did: what they browsed, whether they have bought before, how they responded to messages in the past, what shoppers like them across the category did next. The agent decides whether to message, which channel, when, and whether an offer is warranted, inside guardrails set once, and 100% of flows run without a human in the loop. The priors come from a Large Retail Model trained on 7M+ data points across 10K+ retailers and 1.78M shoppers, so the decision is informed before the store has a history of its own.

The headline numbers: 2–6× ROI in 30 days and up to 10× revenue uplift year over year versus the incumbent platform, with 80% less spam, because the sends that would not have moved a shopper are the ones that do not go out. Two customer examples: Stein Mart, 6X ROI in first 14 days, and Arvin Goods, 4X revenue uplift for Cyber Sale email campaign. Migration takes about 30 minutes and the proof is a 14-day pilot beside the current tool. The how-to for Shopify is in abandoned cart recovery on Shopify, the strategy in cart abandonment email strategy, and pricing on the pricing page.

Frequently asked questions

How to recover abandoned carts?

Capture the shopper's email or phone before or at checkout, detect the abandoned cart or checkout, and send a reminder while the intent is still warm, by email, SMS or push. Every cart tool in this article does that on a schedule; the standard series is a reminder, then a follow-up with a discount, then a recommendation. The per-shopper version decides the timing and the offer for each shopper rather than per flow, because a returning customer needs no code and a price-comparison shopper needs the first message inside the hour.

What is the best abandoned cart app for Shopify?

For a basic automated reminder, Shopify's built-in abandoned checkout automation costs nothing extra: in Shopify's words, “abandoned checkout automations are always free and don't count towards the monthly limit.” For a multi-message series with codes and targeting rules, apps such as Cartly (email reminders and web push) and Recapture (email and SMS) are built for that. For recovery decided per shopper rather than per rule, including whether to discount at all, Relvino replaces the flow and proves it in a 14-day pilot. The how-to is in abandoned cart recovery on Shopify.

How to track abandoned carts?

Shopify records an abandoned checkout whenever a shopper enters an email and does not complete the order. Carts left before the email step are visible only if a tool captures identity earlier, which is what site-wide capture features (CartStack's “Capture emails as they're typed, site-wide”) and pop-ups are for. Track two numbers, not one: the abandonment rate, and the share of abandoners who came back without any message, which is a proxy for how many of the flow's discounted recoveries were not needed.

How to fix cart abandonment?

Some of it is not fixable and should not be: Klaviyo's guide cites “70% of online shopping carts are abandoned,” and many of those shoppers were comparing or saving for later. What is fixable is the response: reach the shopper who is about to buy elsewhere within minutes, leave the shopper who will return alone, and spend the discount only where it changes the outcome. On-site fixes (shipping costs shown early, guest checkout, fewer form fields) reduce the rate; per-shopper decisions withhold the code from the shopper who would return anyway, without training customers to abandon for one.

How long does it take to migrate cart recovery to Relvino?

About 30 minutes for the technical cutover: connect the Shopify store, point the sending domain, connect SMS, and shopper data ingests automatically. There is no cart flow to rebuild; the guardrails and margin floors are set once. Revenue is proven in a 14-day pilot run beside the current tool, which is also where the discounts-not-needed count in this article becomes measurable. Pricing is on the pricing page.
